until the'- projection coincides withthe thereby opening 45, after which the pin is withdrawn. After backing the tractor, the clevis may beinserted and the latch is turned on its pivot, swinging back between tlieplates 33 and 35 until it has passedtlie opening for the pinl41 in said plates. This permits the re-insertion of the pinA 41 in its opening, and tliedevice is again ready for duty. v It is understood, ofcourse, that when the latch is sprung, the triangular plates 33 and 35 immediately return tothe position shown in the drawings because. of the action of the spring `57. -That is the. reason for the re'- inovable pin 41. By this arrangement, there is no strain on the spring except the instant of compression thereof and release of the latch. .This results in very long life ofthe gevity of the spring.
